EQUALZING DEVICE FOR WINDEVHLLS.

SPECIFICATION forming part of Letters Patent No. 581,882, dated May 4, 1897. Application filed September 22, 1896. Serial No. 606,645. (No model.)

To all whom z' '11i/(ty concern:

Be it known that l, LEWIS E. FAGAN, a citi- Zen of the United States, residing at Onslow, in the county of Jones and State of Iowa, have invented a new and useful Equalizng Device for Windmills, of which the following is a specification.

The invention relates to equalizing devices for windmills.

The object of the present invention is to improve the construction of equalizing devices for windmills and to provide a simple and effective one adapted to relieve the pump of any jerking movement and capable of ready adjustment to regulate the length of the stroke to suit the strength of the wind.

A further object of the invention is to enable the equalizing device to be readily connected with the pump-rod of a windmill or a pump-handle and to be adjusted, when connected with the latter, to regulate the stroke `of the pump.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of an equalizing device constructed in accordance with this invention and shown applied to a pump and connected with a windmill pump-rod. Fig. 2 is a side elevation of the same, the equalizing device being connected with a pump-handle. Fig. 3 is a longitudinal sectional View, the parts being arranged as shown in Fig. 2. Fig. 4 is a detail sectional View illustrating the manner of connecting the equalizing device with the pumphandle.

Like numerals of reference designate cor- --rcspondin g parts in all the iigures of the drawings.

1 designates a bracket mounted upon a pump 2 and comprising a top 3, bottom 4, and similar sides 5, mounted on the bottom or base and supporting the top, and the bracket is provided at its top and bottom with openings, through which passes the plunger-rod 6 of the pump 2. The sides 5 of the bracket 1 are forked, as shown, and at one side of the bracket is pivoted an arm or bar 7, forming a fulcrum fora pump-handle 8, adapted when not in use to be swung backward, as illustrated in Fig. 1 of the accompanying drawings.

The base of the bracket is provided at opposite sides with horizontal extensions or lugs 9, arranged in pairs and perforated for the reception of pivots 10, which connect upwardly-diverging fulcrum bars or supports 11 to the bracket. The diverging bars or supports 1l have their upper and lower ends forked, and their upper ends are perforated for pivots 12, which connect the outer ends of a pair of curved levers 13 to the fulcrum bars or supports.

The inner ends of the levers 13 are pivoted together and to a pair of connecting-bars 14 bya pin 15, which passes through registering perforations of the levers and the bars and which is also arranged in a slot 16 of a pumprod casting 17. The slot 16 extends longitudinally of the pump-rod casting, which is provided with a longitudinal slot 18, extending through the casting at right angles to the slot 1G and receiving the inner ends of the lcvers 13.

The connecting-bars 15 are adapted to be attached either to the pump-rod 19 of a windmill to operate the pump by the latter, as illustrated in Fig. l of the accompanying drawings, or to be attached to the pumphandle 8, as illustrated in Figs. 2 and 3 of the accompanying drawings. Vhen the connecting-bars 14 are attached to the pumphandle, the inner ends of the levers are adapted to slide freely in a slot 18 of the pump-rod without moving the latter. The ends 2O of the connecting-bars 14 are detachably secured to the pump-rod 19, and when it is desired to operate the pump by hand the said ends 2O are disconnected from the pump-rod to permit the connecting-bars 14 to be swung downward on the pivot or pin 15 in order that they may be attached to the inner end of the pump-handle. The pumphandle S, which is fulcrumed intermediate 0f its ends on the bar 7, has its inner end 21 bifurcated and perforated for the reception of pivots 22 of the ends 2O of the bars 14. The pins 22 detachably engage the perforations of the pump-handle, and the ends 20 are spaced by a block 23 and are connected by a pin or bolt 24 or other suitable fastening device. The plunger-rod is loosely ar- IOO ranged in the bifurcation of the pump-handle, and it is connected with the levers 13 by a substantially rectangular frame 25.

The rectangular frame comprises a pair of horizontal bars 26, centrally pivoted to the upper portion of the plunger-rod 6, at opposite sides thereof, and a pair of substantially vertically-arranged bars 27, pivoted at their lower terminals between the ends of the bars 26 and having their upper ends bifurcated and adjustably pivoted to the levers 13. The levers 13 are provided at intervals with perforations 28, and the upper terminals of the sides 27 of the connectin g-frame 25 are adapted to be moved inward or outward on the levers 13 to vary the length of the stroke of the plunger-rod of the pump. By moving the ends yot' the sides 27 of the connecting-frame toward the fulcrum bars or supports 27 Jthe stroke is shortened, and to lengthen the strokes the sides of the connecting-frame are adjusted toward the pump-rod of the windmill. When the levers 13 are oscillated by the pump-rod of the windmill or by the pumphandle, the plunger-rod 6 of the pump will be vertically reciprocated, and the equalizing device, which is adapted to regulate the stroke of the plunger-rod, prevents the jerky motion of the windmill being communicated to the pump.

It will be seen that the equalizin'g device is simple and comparatively inexpensive in construction, that it is adapted to be readilyapplied to any'ordinary windmill and pump, and that it is capable of effecting the reciprocation of the pump-rod either through a pump-handle or the lpump-rod of a windmill.

It will also be apparent that it is adapted to take up the jerky motion of a windmill and prevent the same from being commu-nicated to the pump and to regulate the stroke of the plunger-rod of the pump to suit the force of the wind.

The equalizing device is also applicable to engines and motors and may be applied wherever it is desired to obtain a steady reciprocation free from all jerky motion.

Having described this invention, what I claim is- 1. In a device of the class described, the combination with a 'pump having a pumphandle, and the pump-rod of a windmill, ofy the opposite supports or fulcrums, the substantially horizontally-disposed levers piv-v oted at their outer ends to the fulcrums or supports and connected at their inner ends, a connecting-bar pivoted to the inner ends of the levers and adapted to be-attached'either to the pump-rod of the windmill or to thel pump-handle, land means for connecting the plunger-rod of the pump with the levers at points intermediate =of the ends or" the latter, substantially as described.
